In a search for a more satisfactory reaction for detection of guanidinium compounds than is at present afforded by chromogenic reactions we have found that ninhydrin (1,2,3-indantrione hydrate ...

Covalent attachment was confirmed using FTIR and ninhydrin assays, and morphological characterization was conducted via optical, fluorescent and scanning electron microscopy. A complete protection ...

The presence of amino acids was determined by spraying with ninhydrin on TLC plates. 3.2. Amino Acids Sixteen amino acids or related compounds were identified in the honey samples by using HPLC.

The AminoPac® PA1 column is a high-speed, pellicular, strong, anion-exchange column. The PA1 delivers high-efficiency separations as a result of its nonporous-core particle. Its strong anion ...

A GREAT number of abnormal aminoacidurias have now been described, 1 and investigation of such patients has provided better insight into normal human biology. We believe that the following report ...
